What Are Quantum Dots and Why Do I Want Them in My TV WIRED
The chemicals and processes involved in the synthesis of quantum dots are dangerous! We do not recommend anyone without proper training and equipment to handle and process very toxic chemicals to try synthesizing these nanoparticles.

Experimental chemistry is not our forte, so we prefer to use professionally-manufactured quantum dots for the Schrödinger’s Wave Equation experiments we discuss in the ‘s Chapter 7. However, if you are interested in synthesizing your own quantum-dot nanoparticle suspensions, we recommend that you take a look at the detailed instructions prepared by Professor George Lisensky at Beloit College for the (Local printer-friendly copy at: ).

Our data clearly show that the combination of i) the use of graphene with a Ni underlayer and i) the use of SKU-1 as a nanoporous mask makes it possible to synthesize CdSe quantum dots into an array structure on the graphene basal plane. The effects of these two measures can be explained as a decrease in the difference between the resistance at the edge/defect sites and that of the basal plane. The Ni underlayer provides conduction paths so that it can reduce the resistance on the basal plane. The nanoporous SKU-1 mask functions as a diffusion barrier for the incoming ions in the electrolyte solution, which overrides the conductivity difference between the edges/defects and the basal plane. Furthermore, the regular pore structure of SKU-1 functions as a template to deposit quantum dots into an array structure.

Procedure to synthesize a CdSe quantum dot array on the basal plane of a graphene sheet using a mesoporous silica thin film as a template: a) Formation of a mesoporous silica film on the graphene surface by spin-casting, aging, and calcination, b) electrochemical deposition of CdSe onto the graphene surface through the pores of the mesoporous silica film template, c) removal of the mesoporous silica template, and d) removal of the Ni layer underneath the graphene sheet.
